taking out the furniture relieves you of a lot of headaches when you have to work around objects.
Your floor is made up of OSB- oriented strand board. If you get a multipurpose tool for any demo, that will make this project easier. Take an ice pick in the affected damaged areas, after carpet and whatever else hard surface you have removed. If you jab the pick into the floor and it penetrates with ease, move a bit further away to ascertain how extensive the damage is. Then you can start replacing the OSB.

First thing I did was replace the nasty carpet in our new to us class a.
Not easy, but invest inthe a lot of razors,
I left the carpet under cabinets and in the cab area, under the cabinets, the carpet still had protected plastic covering.
Threw down traffic master allure vinyl wood plank with a 1/4 in gap at all walls. Cleaned up with quarter rounds. Used a carpet tucker to push the remaining carpet up under walls n cabinets.
Took me about a week with two kids wanting my attention constantly.
i hear if you have slide outs it gets a little tricky. . Good luck.

When your coach was built, the floor and the carpet were installed first, and then the cabinets and interior finishing work. As a result, the carpet is going to extend under the cabinets. For that reason, we decided not to have our flooring replaced by a contractor since it would have been impractical to have the cabinets removed.

Another problem is the underlayment or sub-floor is of pressboard or particle board construction and may have been damaged when it got wet by swelling up. I understand Monaco used very thick sub flooring, maybe over an inch thick. Cutting some of it out and matching up a new piece may leave a seam or joint that will allow flexing. I wish I could offer a good solution other than taking out everything. Good luck.
